`Application led December 22, 1925. Serial No. 76,986.

Our invention relates to boots and shoes and particularly to the construction of the inner soles thereof, the object of the invention being vto improvethe construction of boots and shoes, and more especially to pro vide an improved inner sole therefor.

In carrying out our invention the, inner sole is made up, essentially, of four soleshaped .members of flexible material cemented one upon the other, the lowermost member consistingof a piece of sole leather to the top side of which is cemented a piece of felt or the like., To the top side of thisv felt vmember is cemented a piece of thin waterproof material and on top of this is cemented a sock sole or cover member which may bc made 'from thin leather or other suitable material. Allvofthese parts are of approximately the same'sizev and. shape ;so that the samedie may be employed to cut out all of them. VThe'felt member provides a cushion for the foot, while'the waterproof member shields the felt from the perspiration of thel foot. In one form of our invention a second waterproof member lsmcorporatedinthe inner sole between the lbottom leather member and the feltto shieldthelatterfrom moisture entering the shoe *from below. Preferably all of. the ,members` are secured togetlieithroughout the shank and fore-part by stitches andthe heel portion of the bottom leather member is left free and unattached to the heel portion of the next member above it until after the heel is affixed to the shoe. Other features of our invention are hereinafter pointed out.

In the accompanying drawings:

Figure 1 is a plan view, partly broken away, of an inner sole constructed in accordance with our invention.

Figure 2 is a side elevation of the heel portion of the inner sole shown in Fig. 1.

Figure 3 is a central longitudinal section of the inner sole shown in Fig. 1.

Figure 4 isa sectional detail illustrating another feature of our invention.

Figure 5 is a sectional view of the toeportion of a shoe provided withour new inner sole.

Our improved cushion inner. sole comprises, essentially, four sole-shaped pieces of flexible material 1, 2, 3 and t, all of which are of approximately the same size and shape, ercept as to thickness..V The lowermost piece 1 is the body member and is preferably made from sole leather and may be `.by cement, either directly or indirectly, to

the top side of the sole leather body member 1, the rear heel portion .of said cushion member being left free. On top of this felt cushion member 2 is a member 3v madet fromy any suitable thin waterproof sheet material such as cloth, paper or the like, treated to make it waterproof, and this member .is cemented throughout its. area-forepart, shank 4and heelto the top side of the felt cushion Amember 2. The' top member, or socksole, L

is preferably a thin. piece ofleather such as sheep-skin, or .other suitable sheet material, cemented throughout its area .to the top side of the `waterproof member 3.

After assembling the parts as above describedthey are-further.secured together .at their edges, but only throughout the shank and-v fore-part .of the solo, by margin- Aal stitches-11 extending throughtheseveral members andalso cast around. their edges, so that the edge portions of the sock sole member l and of the body member 1 are drawn together thus inclosing the felt cushion member throughout the shank and fore-part.

Figure 5 is a sectional view of the toe portion of a shoe provided with an innersole constructed in accordance with our invention, and as seen in that figure, the welt 8, upper 6 and lining 7 are stitched, as usual,

to the lip 5 upon the bottom side of the body member 1. In this figure 9 is the outersole stitched as usual to the welt 8, and 10 is the usual lling placed between the inner and outer soles.

The heel portion of the felt cushion 2 is left unattached to the body member 1 so that said heel portion, and the heel portions of the waterproof member 3 and sock sole 4:, may be bent aside during the operation of aiXing the heel to the shoe, after which operation said heel'portions are returned to their normal positions and the cushion member is cemented to the body member 1, thus covering the inner ends of the heel nails.

The waterproof member 3 serves to prevent the perspiration of the foot from reaching the felt cushion and, being cemented to the felt member throughout its area, serves also to hold the latter in shape and to prevent it from shifting. In another form-of Bythus protecting the felt from all moist-ure it is keptdry and does not, therefore, mat or lose its resiliency.

Besides strongly and positively uniting all of the parts of the inner sole, the stitches 11 also serve to reduce the thickness of the in ner sole at its margin throughout its shank and fore-part by drawing the edge portions Y? of the members l and l together, and to prevent the edges of the several members from loosening and' curling up, or the felt from working out from between'the members l rand 3.

While we have herein shown our improved inner sole as incorporated 1n a welt shoe, it will be clear that with slight modiflcation it may be adapted to any other type of shoe made from either leather or rubber.

Whatwe claim is:

1. An inner sole comprising a leather soleshaped body member; a sole shaped top member of soft flexible sheet material; a sole-shaped felt cushion member between lthe top' and body members; a sole-shaped all of the same size and shape including a leather sole-shaped body member provided upon its underside with a lip for attachment to the upper and welt of a shoe; a sole shaped top member of soft flexible sheet ma- Y terial; a solewshaped felt cushion member between the top and bodyy members; a soleshaped waterproof member of' sheet material between the top and cushion members and cemented throughout its area to both of said members; a ksecond sole-shapedv waterproof member of sheet material betweenthe body and cushion members cemented throughout the areaV of its top side to said cushion member and cemented throughout only the shank and fore-part portions of its bottom side to said body member, and marginal stitches fastening all of said members together but konly throughouttheir shank and fore-part portions, said stitchesbeing cast around the edges of said members and holding the edge portions of the top and bodyy members together so as to inclose the cushion member. y

In testimony whereof 4we have affixed our signatures.
